Here's my code. The error asks if I forgot to create a method that accepts a char

I don't know if i understand the task correctly. The error seems to indicate that the method should take a char as a parameter?

ScrabblePlayer.java
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }

  public int getTileCount() {
    int tileCount = 0;
    for (char tile: mHand.toCharArray()) {
      if(hasTile(tile)) {
        tileCount = tileCount + 1;
      }
    }
    return tileCount;
  }
}

The error is correct. What you need to do is have the function accept a char

public int getTileCount(char inputChar)

Then instead of using hasTile to check you need to compare the char you got from the input to the char you are on in the loop.

for (char tile: mHand.toCharArray()) {
      if(tile == inputChar) {
        tileCount = tileCount + 1;
      }
    }

So you should end with something like

public int getTileCount(char inputChar) {
    int tileCount = 0;
    for (char tile: mHand.toCharArray()) {
      if(tile == inputChar) {
        tileCount = tileCount + 1;
      }
    }
    return tileCount;
  }

Goodluck! --Ricky

Thanks a lot to you both! That did it!

Yes you should pass a char in to getTileCount. The idea is to say something like how many 'b's are in my hand.
